Because I'm a geek, that's why

Here are the fronts and backs of my collection of arcade tokens from the early 1980s. I used to have many more, but this is what's left. The O'Hare token says 1992 not because it's from that year (it's more likely from around 1983), but because Chicago at one time was supposed to have a world's fair in 1992, back when American cities still had world's fairs.
